INDUSTRIAL TRUCK.

Original No. 1,439,233,.dated December 19, 1922, Serial No. 493,799,filed August 20, 1921'. Application for reissue filed December 20, 1923.Serial No. 681,889.

The general object of the present invention is the provision of a loadengaging mechanism, on an industrial truck adaptable for the loading,unloading and transporting of loads, which will automatically secure theload against displacement when the latter is being engaged ortransported by the truck.

A further object of my invention is the provision of a load carryingmechanism on an industrial truck which may be moved,

relative to the body of the truck to raise the load, by a load carrieractuating mechanism acting upon the carrier indirectly through a loadsecuring means, which, when actuated secures the load in position uponthe carrier before the carrier is moved relativeto the truck. i I p Astill further object of my invention is to so arrange the foregoingcombination of mechanisms upon an industrial truck that the operator maymaneuver the truck to approach .a load while remaining in positionthereon and to cause the truck to engage and lock the load beforeinitiating a trans portable movement of the load.

Other objects will become apparent from the following description whichrefers to the accompanying drawings illustrating an adaptation thereofto an industrial truck equipped to handle large or heavy paper rolls.The essential characteristics are summarized in the claims. r

In the drawings Fig. 1 is a side elevation of a truck such as I havereferred to; Fig. 2 is a plan view of a load engaging mechanismpositioned on one end of the truck; 'Fi 3 is'a front elevation of a loadengaging an securing means; Fig. 4 is a cross-sectional elevation takensubstantially along the lines 4-4= Of,Flg.3 Fig.5 is a transversesection taken through the load engaging means substantially on the line5-5 of Fig. 3; Fig. 6 is a view similar to Fig. 5 but showing the loadengaging parts in adifferent position, and Fig. 7 is a section takenalong the line 7-7 of Fig. 3'. i

Self-propelled vehicles have been adapted to a great variety ofindustrial uses in and about manufacturing plants, commercialwarehouses, railroa'dtermini, -etc., and are commonly referred to asindustrial trucks.-

The nature of my invention is such as to be readily adaptable to avariety of forms of such trucks. An adaptation thereof, as apinventionmay be adapted to any type of industrial truck which is provided withmechanism for elevating a load upon a load sup-.

porting medium.

I In the type of truck illustrated in the drawings, ituis important,that in order to use the truck efficiently in handling'paper rolls, therolls must be engaged by the truck insuch manner that a sufficientclearance space may be present about the circumference of the rollswhereby large rolls may be positioned in juxtaposition in warehouses,railway cars, et-c., without necessitating any physical effort on thepart ofthe operator excepting that required to manipulate the controlmechanism of the truck. The use of my invention greatly facilitates thecon struction of a truck which will fulfill these requiredcharacteristics.

In the drawings in Fig. 1, I show such a truck which may have a body orframe 10 and an upright frame 11 preferably pivotally mounted at one endof the frame or body 10. In this particular type of truck the loadengaging means may comprise a load supporting member 14 conforming ingeneral shape to the approximate dimensions of the rolls to be handled.This load supporting member may be pivotally mounted on the uprightframe 11. The pivotal connection between the upright frame 11 and loadsupporting member 14 is located in such manner that when the frame 11'is swung inwardly over the truck the load supporting member may be swungeither into a substantially upright position or to 'a substantiallyhorizontal position while supporting the load. I

The means for effecting the swinging movements of the load supportingmember 14 and the upright member 11 may comprise a power operatedwinding mechanism conventionally shown at 12 and a flexible member 13.The-end of the flexible member may be secured to the load'supportingmember flexible member a turning movement of the load supporting member14 may be effected relative to its supporting medium. Hence the load maybe received in a horizontal position. This connection may be so located,

however, that the reactive forces upon the members 11 and 14 will besuch that the upright frame 11.may be tilted inwardly before the loadsupporting member is caused -to swing upon-its pivotal mounting, thuscausing the member 14 toclear the ground or floor when being swung. Theinnermost position of the upright frame 11 is indicated by the dot anddash lines in Fig. 1. Suitable cushioning .means, such as telescopicmembers 16 and spring members 16, may serve to limit the inward andoutward swing of the frame'member 11. Thespring members 16 also serve toposition the frame 11 the rolls may be stored or deposited in uptheapplication for vertically when the winding mechanism is released.

A truck having the general'characteristics herein described is fully setforth in Letters Patent of Clyde E. Cochran on an industrial truck filedJanuary 9th, 1920, Serial No. 394,933, whose ended-position andjuxtaposed to one another. The span of the load supporting member hereinillustrated is of sufficient width, however, to permit proper supporting and securing of the rolls while afl'ording rigid connection to apivot member 17 which is associated with the pivotal hearing mechanism15 carried by the upright frame 11. This'decrease in the dimensions ofthe load supporting member 14 is made possible by the adaptation of myinvention to the particular problem here encountered, namely theobtaining of sufficient strength in the load en aging 'member to supportheav loads an proper clearances whereby the oads may be deposited in themanner described to save floor space.

An adaptation of my invention to a paper handling truck will now'bedescribed:

My invention contemplates the use of a load securing or' clamping meansand a load elevating and supporting means which are actuated in sequencebya power operated means, the force to elevate the load, being firstexerted upon the load clamping means and while being maintained thereonto they load supporting means whereby a load elevating movement of thelatter is which is adapted to-lie in-a horizontal posi-' tion on theground or floor, when the load supporting member 14 is in asubstantially position. In this particular instance the pro ectlngportion may have a tapered edge 19 to facilitate the forcing thereofunder the load or paper roll by a backward movement of the truck.

In the present form of my invention the load clamping means may comprisea load gripping member 20 preferably flat and having' a general shapecorresponding to the shape of the projecting portion 18; The member 20may be mounted upon a mechanism which may be actuated by the flexiblemember 13. This mechanism may comprise an angle member 21 supporting thegripping member 20 and adjustably secur'ed to a member-22 slidablymounted upon the upper portion of the load carrying member 14, .as shownin detail in Figs. 2 to 6 inclusive. The slide member 22 may be retainedin an elongated opening 23 formed in the load carrying member 14 byreenforcing bars24 and 25 rigidly secured to the latter. The endof thecable 13 may be secured to astud 2 rigidly attached to the slide member.i order that the cable ma impart a downward movement to. the slidemember it may be'extended over a sheave member 33 positioned on the loadreceiving member 14 below the slot 23. The proper positioning of thesheave member 33 is likewise dependent upon the amount of torque whichwould be required to rotate a maximum load carried by the member 14about its pivotal axis or bearing 15, the latter action taking place ofcourse if the load is being received horizontally and after the member20 has been brought into engagement. with the load or roll R.

The slide member 22 may have the lower end thereof turned out to form aseat 29 affording an abutment for a resilient member 30. The resilientmember 30 thus serves .upended or a load receiving and depositing Thespring 30 likewise serves to cause the clamping member 20 to be elevatedout of engagement with the load when the cable is slackened consequentto the load supporting member bearing upon the ground or floor. v I

Any convenient means may be provided to afford adjustability between theslide member 22 and the angle bar 21 which supports the gripping member20. As shown in Fig. 4 the removable bolts 48 are shown as ex-- tendingthrough two of a series of openings 49 formed in the upper end of theslide member 22, thus affording adjustment of the gripping member forrolls of any length and within the weight capacity of the truck.

It will be seen that the lowering or load engaging movementof the slidemember 22 and gripping member 20 is automatic and dependent upon theoperation of the upright frame 11 and load supporting member 14 by thecable, and that this automatic action is incident to the eleva'tingmovement of the load. by operation of the winding mechanism 12. It willbe also apparent that the gripping or clamping action of the member 20may be directly proportional to the weight.

of the load being handled. Furthermore it will be seen that as thewinding mechanism 12 draws in on the flexible member 13 to tilt theupright frame 11. the cable will move sufficiently to draw the member 20downwardly into engagement with the upper end of the load, whereby asufficient gripping force'will be obtained between the projectingportion 18 and'the top clamping member 20 to secure the load on the loadcarrying member 14, before any tilting or elevating movement of theupright member 11 takes place. A further drawing in movement of thecable will then tilt the frame and load supporting member inwardly overthe truck. The telescopic members 16 serve to resil- 'iently oppose thistilting movement a sufficient amount to always maintain a considerable.tension in the cable, hence the gripping member is forcefully maintainedin engagement with the load during the load elevating, tilting andlowering movements.

If it is desired to rotate the load from this inclined position, thatis, the transportable position When the member ll is tilted, to the "dotand dash line shown, to a substantially horizontally position and thendeposit it, the frame 11 may be retained in the tilted position by asuitable, latch mechanism (not shown) and as the cable stretch isgradually released bythc winding mechanism the load and load supportingmember will be swung downwardly to a horizontal.

position. The center of gravity of the load and frame. 11 may be "sodisposed with relation to the rotating axis of the load supportingmember 14, as to effect this swinging movement by gravity. The relationof the various parts whereby they are adapted to obtain this result isdescribed in the Cochran application hereinbefore referred to.

1n the present instance. due to the decrease in the circumferential spanof -the load receiving or supporting member .14, it is desirable that anextension be provided on the member 14 to support the load along thesides when being swung or lowered into sheave members 39 and 40 mountedthereon,

sliding engagement with the load supporting.

member 14 by properly formed straps-'35 and 36 rigidly secured totheload supporting member. The position of these members may besubstantially halfway between the bottom projection 18 of the, loadsupporting member and the gripping member 20 and may also be such thatthey may be manipulated by the'operator from his position on the truckby means of a. flexible member 37. The flexible member 37 may havesuflicient slackness to permit the retention of a looped portion thereofby a sheave member 38 positioned at the front of the truck. When theload supporting member 14 is being rotated about its pivotal bearin axis15 may serve as a guide means for this flexible member. The ends oftheflexible member may be attached to connection plates 41 and 42 scured tothe ends of the arcuate load supporting members 34. Thus the operatormay slide the members 34 tothe extended position illustrated in Figs. 1and 6 prior to the raising or the lowering of the load from or to ahorizontal position or if it is desired toapproach a roll standing invertical juxtaposition to another roll the operator may slide the member34 in an arcuate direction about the load supporting member 14 to aninward or retracted clearing position, substantially as shown in Fig. 5.

It will be seen that the extension arm 34 affords a very convenientmeans for receiving the load upon the trunk' when the load supportingmember 14 is swung to a horizontal position and the upright frame 11 ispermitted to swing upwardly to a substantially vertical position. Themembers 34 in this instance would be extended and would thus be loweredto contact with the ground or floor. The ends 44 thereof may be roundedwhereby the load may be rolled over these ends when a horizontal load isreceived. When a horizontally disposed load is deposited on the member14 the winding mechanism functions in the manner hereinbefore describedin causing the cable to firstact on the gripping member 20 to bring itinto engagement with an end surface of the roll. The roll is thengripped between the member 20 and the end portion 18 of the loadsupporting member before any elevating or swinging movement is impartedto' the upright member 11 or the load supporting member 14 respectivelyand is continuously clamped in position whether it is being swungupwardly from a horizontal position to an inclined posit-ion by movementof the load supporting member or. is

being tilted inwardly to a transportable position on the truck bymovement of the upright member 11. a

From the foregoing description of a specific embodiment of myinvention,it

. member is raised.

would seem that extremely eavy loads may be loaded and securedautomatically in a transportable position on a truck regardless of thedisposition of the load relative to other or similar articles to behandled. The

load may be taken up from either a vertical or horizontal position,elevated to .an inclined transportable position on the truck andsubsequently may be deposited in either of those positions withoutnecessitating any manual effort on the'part of the truck operator, otherthan the manipulation of the flexible member 37 and the usual levers Iwhich control the movement of the'truck and the operation of the windingmechanism.

It will also be apparent that my invent-ion, while being hereindescribed as speci cally applied to a truck constructed for theparticular purpose of handling large paper rolls, is adaptable to avariety of forms which may be conveniently applied to other types ofindustrial trucks, such as elevating platform trucks, tier lift trucks,etc.
